目的对燃煤型氟中毒改灶后5年居民室内的主要携氟介质的氟含量进行综合评价,以此论证监测方案的可行性。方法按全国统一监测方法,每年同一时间对我省5个重点监测点进行调查,包括采样分析。结果室内空气氟的一次性检测结果与同期检测的室内食物氟含量的结果不相吻合。虽然空气氟含量有所降低(0.0013~0.0142mg/m3),但室内玉米,辣椒氟含量在不同年份间仍有回升,8~12岁学生尿氟含量亦保持在较低水平,氟中毒病情监测呈下降趋势。结论在对燃煤污染型氟中毒病区的改灶后监测时,除观察儿童氟斑牙率和尿氟含量外,内环境污染的考核应以室内存放的主要粮食氟含量的升降为评价依据
Objective To evaluate the feasibility of the monitoring program by comprehensively evaluating the fluoride content of the main fluoride-carrying medium in residents 5 years after the coal-fired fluorosis was changed into a stove. Methods According to the unified national monitoring method, five key monitoring points in our province were investigated at the same time each year, including sampling and analysis. Results The one-off test of indoor air fluorine did not coincide with the result of indoor test of fluoride content in the same period. Although the air fluoride content decreased (0.0013 ~ 0.0142mg / m3), indoor corn, pepper fluorine content still rose in different years, 8 to 12-year-old students urinary fluoride content also remained at a low level, fluorine Poisoning disease monitoring showed a downward trend. Conclusion In the monitoring of the coal-contaminated fluorosis area after the stove is switched on, in addition to the observation of children’s dental fluorosis rate and urinary fluoride content, the assessment of the internal environmental pollution should be based on the indoor storage of the main food fluoride content as the basis for evaluation
